why are some colours commonly found as surnames (white, brown, green) but not others (red, blue, yellow)

Question

And furthermore how does language play a part – I know red (rojas/rossi) is a Spanish and Italian surname but not English

In: 2480

Answer 1

In Spanish I’ve met:

Rojas
Negrón (Big black?)
Blanco (White)
Laverde (The Green one?)

But no Marrón.

No idea why that is.
